IMHO, the token ring is a superior protocol! It is deterministic, one could allocate bandwidth and priority to a given node, and many other benefits. The problem was marketing ant the greediness and over protection of IBM.
And look at the current Ethernet! Just a point-to-point, switched network, with a single point of failure.
Should also point out that the triumvirate of Digital Equipment Corp. (DEC)--remember those guys, Intel, and Xerox also had a hand in creating the 10-Mbit Ethernet standard that prevailed over the IBM token ring network and others. Funny how much history gets lost in time.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
